"The fundamental way data is stored in Chandler is as a collection of items, also known as a repository. Every individual email is represented by an item, as is every meeting on a calendar, and every contact. Not only that but every attachment, document, and annotation is also an item. In short, each piece of content is represented as an item." Judging from the comments, this is a popular notion (though still "new," compared to most of the apps we run). My addition is that this description of Chandler could almost all apply to the old Pyra app, as well, though that was primitive in comparison (and a web app). Trying not to buy into the hype, but I'm more intrigued by this Chandler fellow daily.
